Gouilles- Del (Saint-Denis)

Setting off from Gouilles (628 m) in the municipality of Châtillon, the trail climbs the sun-drenched south-facing slope overlooking the confluence of Valtournenche and the central Aosta Valley. The route follows country paths and old mule tracks through well-tended vineyards and orchards before entering the warm, dry scrubland of downy oak and Scots pine typical of this sheltered aspect. The 623 m gain over just 3.5 km gives the ascent a consistent, sustained character. Views broaden steadily toward Châtillon, the Ussel castle and the peaks closing the Valtournenche to the north. The trail ends at Del (1251 m), a quiet mountain hamlet shaded by fresher mixed woodland. Best walked in spring, autumn or early summer.
